To all whom it may concern Be it known that l, Jenn Roman Primes. acitizen of the United States of residing at New York, in the county ofew York and State of New York, have invented certain new and usefulImprovements in Perforation-Reading lnstrumentalities, which thefollowing is a full, clear, and exact description.

This invention relates to machines controlled by perforated record cardsor sheets and has for one of its principal objects to provide novelcombinations of instrumen- 'ties to sense or read the perforations ofthe record.

Another object is to decrease the number of working parts of suchmachines.

A further object is to render such Ina-- bit chines more compact. Gtllerobjects and a antages will appear as the invention is 'L .iereinafterdisclosed.

Referring to the drawings which illustrate what 1 now consider to be apreferred form of the invention Fig. 1 shows a record sheet, in the formof a card, of the type adapted to he employed in ccntrollingthe machine.

application died June '2 printed record and a perforation record may bejointly obtained.

Figs. 16 and 17 are detail views showing certain of the operatingdevices.

While the novel form. of record sheets employed and the novel system. ofperforating the same are embodied and claimed in separate companionapplications entitled Ideoord sheets and apparatus controlled therebyand Method of and apparatus for per foratin' record sheetsg j: shallsomewhat generally describe such sheets and system in order tofacilitate disclosure of the present invention.

Referring to Fig. 1 it will he seen the record sheet is there shown inthe form of a card having one or more fields 19%, EKG l, etc. Adescription of one of these fields say the field 106, will suffice inthe present application. This field consists of. a cum. her of rows orvertical columns of hole spaces. Each of these columns of hole spaces isadapted to he perforated to torn; various combination arrangements ofholes or perforations for each row or colunm. Such a card is adaoted tobe fed to a chine provided with rows or columns of perforation-sensingor reading devices which are operated in accordance with the particularcombination arrangement of tions in any row of hole spaces on the cardrepresents a character corresponding to that combination arrangement.And each card column must have a sufficient number hole spaces toaccommodate a number of different combination arrangement of holessufficient to cover the range of characters to be dealt with. In thepresent case ll desire to efi'ect records of any of the letters of thealphabet and anyof the digits and at least one punctuation mark. Thissitates the use of at least thirtydive difierent combinationarrangements of perforations or holes and each card column or row ofhole spaces must be capable of accommodating any of these thirty-fivedifferent combination arrangements.

I have devised a card and system of perforating the same whereby thenumber of hole spaces employed is the theoretical minimum number toaccommodate the various required combination arrangements of penforations. l employ six hole spaces in each to represent the various 26hole 5 ace.

may be provided in any tersinaking up the name tions taken two at 60 forthat hole space 6 hole space system row or vertical column where it isdesired to represent any of the letters of the alphabet and the digits.With six hole spaces it is 'ble to secure sixty-three diii'erent com- 6ination arrangements of perforations.

This number will suiiice to provide distinct records for the variousletters of the alphabet and the digits and punctuation and othercharacters. Five hole s aces will not suffice otters of the alpha-- betand the digits because the maximum possible number of differentcombination an rangemente or holes. in a five sp column or row is thirtyone.

"In Fi' 2 I have shown a preferred code. Each 0 the squares represents ahole'space and each of. the circles represents a hole or perforation.The combination arrangement of holes in any vertical row of hole spaces20 corresponds to or represents the character 'hat row or col- R isrepreindicatcd at the bottom of urnn. Thus, the character sent/ed by twoicrioraiions, one in the second hole space and the other in the fifthThe character E is repre sentcd oy three perforations, one in the second hoie space, cnother in the fifth hole in the sixth hole space,

space and the otber and so on. Each or thirty-dive diflerent 30characters is represented by a corresponding one thirty-five differentcombination arrangements of perforations. it will be understood, oicourse, that any of the various combination arrangements of perforationsof the vertical colthe field of the card. By refer- 1 it will be seenthat various of holes there ilrepresent the let-- *Wiiliam Sevin.Eteierring again to Fig. it will be noted that no inore'than three holesare employed to indicate or represent any of the desired characters.Combination arrangements of sinus of once to Fig. combinationarrangements lustraind, the field 1%,

- four, five or SEX pcriorations might be employed but I prefer toexhaust the number of winbination arrangements of perforations taken oneat time and the numof combination arinngements of perfora .inie, etc,before utilizing higher combination. arrangements of holes,

In other words I not only employ the theoretical minimum number (six) ofhole ll} spaces to represent different characters, in- V cluding theletters of the alipliabet and other characters, but the maximum number(three) of holes employed at any one time to represent a character istheoretical minimum system. Furthermore the total number of perforationsemployed to represent all of the various characters (thin ty-fi've intic iresent case} is the theoretical minimum number (seventy-eight) forthe employed; it necessarily follows that the average number of holesemployed to represent the various characters is the theoretical minimumnumber for the hole space system employed. At this point it may befurther pointed out that characters which are apt to occur arerepresented by single perforations, those occurring less frequently, bytwo perforations, and so on.

It will be noted further that whereas all six hole spaces are employedto represent various letters, only the four up rhole spaces are employedto represent t e digits and the maximum number of holes to represent anydigit is two.

The present application relates particularly to machines adapted toreceive reco sheets such as the card above described and to becontrolled thereby. Such machines may be employed for various purposesamong which is the production of records corresponding to thecombination arrangements of perforations in the record sheets. in otherwords, while the machine selected for the purpose of illustration hereinis particularly adapted for efiecting a recor or records, by printing,embossing, ing or otherwise, such record to correspond to thecombination arrangement of holes in the controlling sheet or card,certain features of the invention are capabie of other uses. 3

Perforation-sensing elements.

to each of the other rows and the instrumentalities operated orcontrolled thereb a specific description of one set will en no for all.

Referring to Fig. 3 it will be seen that the row or column ofperforation sensing elements there illustrated consists of six pins 128.In order to guide the pins 128 through the card, a perforated guideplate 350 is provided. After the particular field of the card hasbeeuread or sensed the pins are withdrawn from the card and the latterremoved. The mechanism for moving the card is fully disclosed in myfirst mentioned application and need not be further descri herein. Thepins 128 extend through lpin guide 350 and are provided with col is 352secured thereto which are pressed against the actuating and restoringmost frequently mosses frame 353 by springs 356. The other ends of thesprings 356 bear against collars slidahly mounted on the pins 128 andwhich sent against a stationary guide plate TAG advance of the pins 128into contact with the card 100 is accomplished by movi ilie frame 353forwardly, permit-ting i: springs 356 to push forwardly those f the pins128 which align with perform iions in the cord.

heard be borne in mind that the t'rsme 353 is adapted to advance 2. bankor series of sets {or vertical views) or elements 128. The means formoving the frame 353 at the proper time in the cycle of operation 'Wilibe hereinafter more speci'ficaily mentioned.

Each of the pins 128 (see Figs. 3 and &} ext-ends rearwardly from theplate 355-and has secured thereto a collar 362 against which 21compression spring 363 abuts. The rear end of each pin 128 is connectedto a ccrrespoi'iding one of sin movable stop members or pin bars 365,367. The first, third and fifsh ins 128 are each connected to acorrespon ng one of three stop members or 1 lo the second, fourth andaims 128 are each connected a. come i one of three pin hers 361'".

Besides thesix pin. bars 365, 367 there are provided three auxiliary pin bars 868.Each three auxiliary pin bars 368 is superimposed upon a correspondingone of the pin bars 365'snd each bar 368 carries lug to which owrresponding one of three tension springs 370 is connected. Each of thelugs 369 extends in the path of forward. movement; of a correspondingpair of three pairs of pins 371372, a pin 371 of each pair beingprovided on a corresponding one of pin bars 365 and the other pin 322 ofeach pair being provided on a. corresponding one of the hers 367. Thevarious pin bars are slidzibiy mounted in a pin. bar frame 375 to whichthe rear ends of springs 370 are connected.

3 shows the normal position of pins and pin bars with no pins advanced.The rear ends of the nine pin bars extend into the path of and controla. plurality of combs A, B and C. These combs are individually slido blein. c direction at right angles to the direction of movement of thepins; and pin bars and each is provided with a laterally extending lugadapted-to cooperate with the three groups of pin bars. In the normalposition of parts With no pins actuated, illustrated in Fig. 3, the lugon the comb A overlies the top pin bar 368, the lug on the comb Boverlies the second pin bar 368 and tlielug on the comb C overlies thelower pin bar 368.

Referring now to Fig. 5, a. condition is here shown in which the comb Ahas de scended one step. This is the result of forward movement of thesecond pin 128 and its connected pin her 367, thereby causing the pin372 of the latter to move the ooopcrsting lug 369 and its pin bar 368 tomove forwardly (or to the left). Under these conditions the pin bar 365remains in nor- Incl position and arrests or limits downward movement ofthe comb A- to c drop of one step. This condition corresponds to asingle perforation in the second hole spme in the cord which representsthe character 5 (see Fig.

the upper pin 128 moves forward clone, the ports assume the positionshown in Fig. 7. Here the bar 365 has moved forward end her 3G? remainedstationery. The in 371 engoges the lug 369 so that the pin are are end365 move together for- Wsrdiy. This siiovvs the comb A to drop twostcpssnd corresponds to e single perforation m the first. (upper) holespecs or the card, representing the character 0.

In 8, both of the two upper pins 128 have moved con-sing ell three ofthe corresponding sin here 3%? to move force A to drop its fullestextent which is limited by e. fixed or stationary adopted to ext-endinto a. cut-out portion on each of the combs.

The condition illustrated in 8 results from forward movement of thefirst and second pins 128 in response to first and sec- 0nd perforationsin a card, rep-resenting the character 9.

Thus the comb A is adopted to occupy fonr diiferent positions in.accordance with the operation of the two upper pins 128. ii hen neitherof these pins moves forward, the comb A occupies the position shown inFig. 3; when the second pin 128 moves forward and the first pin remainsinv normal position the comb A. occupies the second position; when thefirst pin is operated to the exclusion of the second the comb A occupiesthe third position; and when both first and second pins are actuated thecomb occopies the'r'ouztii position. Sin'iilarly the comb B is adoptedto occupy so one of four positions denendent upon the operation of 365end ermittmg the oomb stop member 39% Q pins 128.

be noted that sixty-three diiier- It should cut combinations of the pins128 may be operated. There are sixty-three correspondtype carrier (thereis one the notch ing different combinations of pin bars 368, 365, 367operated one, two, three, four, five and six at a time. And there aresixty-three different combinations of comb positions (excluding the onein which. all three combs are in normal position each determined by acorresponding one o the sixty-three combinationsof actuated pin bars. Inthe present machine I do not employ all of the possible combinations butonly thirty-five of them in accordance with the various combinationarrangements of perforations illustrated in the code chart shown in ig.2.

The combs A, B and C are aided in their descent by the pull or biasimparted. to them by tension springs 37 4. Disposed below the pin barassembly is a group of individually movable feeler members 76. Each ofthese members or feeler bars 376 is slidably mounted in a frame 377 andbiased to the right (Figs. 3 and 5) by a corresponding one of springs 378 secured at opposite ends to the feeler bars and frame 377. Bails 37 9co operate with shoulders on the various ieeler bars to move the latterto, and hold them in,

the position shown in Fig. 3 in which their right hand ends aresubstantially flush with one of the plates 377.

When the bails 379 move to the right and release the feeler bars (seeFig. 5) the advance of the latter is controlled. by the combs A, B andC, which in turn are controlled by the in bars and pins as previouslydescribed In the machine disclosed the combs are rovided with variouscombinations of comb slots so as not onl to select which one of thefeeler bars shal be permitted to advance (to the right) in accordancewith the combination-comb-position, but also the extent of advance ofthe particular ieeler bar. In order to ex lain this control more "full Ishall first re er to one form of record e ecting means.

A type carrier 385 is mounted for vertical sliding movement in suitableguides. This for each set of pins, in bars, combs and feeler bars) isrovi ed with a stepped shoulder 387 havmg three upper steps and a lowernotch 388. When the type carrier is in lower position 388 aligns withthe lowermost feeler bar 376. This lower notch is utilized to preventelevation of the type carrier 385 when there is no perforation in thecontrollin column of the card. Under these conditions a lug 389 on thelowermost color bar is adapted to advance into the then registeringnotches 390 in the comics 1%., 1E and If any of these combs has droppedone or more of the notches 390 will be out of alignment with the iug 389and the lowermost feeler bar will be prevented from advancing into thenotch 388 to lock the t pc carrier.

The type carrier 385 is hiasc to upper position by tension springs 386and when released will assume one of thirty-five different positionsdepending upon which of the upper fourteen feeler bars 376 has advancedand the extent of advance of that bar. In each of these thirty-fivedili'erent tions, a corresponding one of thirtyfive type bars 393 isbrought to the printing plane P P. Each of these type bars is adapted toprint a character corresponding to the combination arrangement of cardpericra tions which causes that particular type her to be positioned atthe printing plane,

It will be noted that each of the f eier bars 376 (see Figs- 9 and iii)"preside-5. with 9. lug 389 which extends acrsss ail. three combs A, Band C. To facilitate explana tion I shall now refer to Figs. 11 to 14inclusive which illustrate diagrammatically but clearly certain of thevarious combination controls. In these iast mentioned views the combs A,B and G are placed in one )lil'flfi and the lug 389 on each feel'er baris s -own as three lugs.

I shall now explain the relative position of parts to effect recordingof the characters N and 6. The recording of of these three characters isdetermined. "53 g the seventh. ieeler bar 376 (counting irnm the top)and this is the :Eeeler bar iilns" trated in Figs. 11 to 14.

In Fig. 11 none of the combs A, B and C have dropped. This is the normalor no-perforation position oi the combs. In

this condition the lug 389 on the ieeler bar will abut the unnotchededge of the B comb and consequently the ieeler bar will not ad vanceinto the path of the stepped etc; 37 of the type carrier. As previouslyex a the lowermost feeler bar will prevent e tion of the type carrier atthis time.

Fig. 12 shows a condition in which the B comb has lowered one step, twosteps, and the A comb two steps. This is indicated by the arrows and isdetermined by the combination of arrangements of perforationsrepresenting the character V (see Fig. 2). In other words the first,fourth and fifth pins 128 will have advanced andpin bars and comb theposition shown in Fig. 5. In this position of combs (Fig. 12) a deepnotch 390 on the B comb aligns with the lug 389, a shallow notch 391 onthe G comb aligns with the same lug 389, and a medium depth notch 392 onthe A comb aiigns with said lug 389. The feeler bar therefore advancesone step as shown (Fig. 12) and engages the first the C comb s will haveassumed accuses & step on; the shoulder 387, whcn the type As statedabove, it should be borne in carrying the letter presented to thecarrier is permitted to be elevated, placing the V type 393 the printingplane P -P.

When the first fourth and sixth pins 128 advance, in accordance with acombination arrangement perforations representing the character l l thecombs assume the positions shown in Fig. 13. Here the B and G combs haveeach dropped one step and the A comb two steps. The l3 and A comhs arethe same position as in Fig. 12 but the C comb is in a (iilferentposition in which it presents a medium depth notch 391 to the lug 89.This permits the feeler bar 3W) to advance two spaces from normalposition, stoppint the stepped stop 387 on the second step. .fhisdetermines a position of the type carri r in which the type slug N ispresented at the printing plane PP.

Fig. 14: represents the position assumed when a combinationarrangementof perforations representing the number 6 is'ierforation-sensing elements 128, The first and. fourth pins 128respond to these perforations and cause the pin bars to be; set as todetermine that position of the combs illustrated in the last namedfigure. Here the B and 1A combs are in the some position as in Fig. 13but the comb is in norinel position. Three deep notches 390, 391' and392 on. the B. C and A. combs respectively, are now presented to the lug389 ancl the pin em is permitted to advance to extend into the pathflofthe top step of the stepped abutment; The type carrier 385 will now bestopped in such position as to present a type slug carrying the number 6at the printing Tclane ?---P.

The relative positions of parts to set the tie printing plane P-P, inaccordance with the I articular combination arrangement oi i erationsncecl not be specifically cle- -becl. Suthce it to say that the combs A,.3151 C are notched throughout their en length with varying depthnotches to coo scrate with the various feeler bars. Each fee er barcarries a proper lug 389 which extencs across the three combs and the 11- inatio s of positions of the comb notches their depth determine thedifiierential advance of the feelcr bars and. thereby tlete mine theextent of elevation of the type carrier It will be seen that the extentof elevation of the carrier 385 thereforethe selection of the typeslugs) is con trolled by two factors. The first factor is the positionof the particular feeler her selected with respect to the remainingbars. The other factor is the extent of of the particular feeler bar selcctcct.

(lo notcorrectly ilustrate the specific construction anal relation of parts.lnstea& of the A, B and G combs lying in the same plane they are mountedas indicated in Figs. 9 and; 10, and instead of three lugs 389 on eachteeter" has there is but one such lug on each feeler bar, which lugextends across all three combs.-

lhe six pins 128, the nine pin bars, the three combs, the fifteen feelerbars and the type carrier, shown in Fig. 3 constitutes set ofinstrumentalities for sensing any of tliirt -five clifierent combinationarrangements of perforations in a card column and for efieoting aprinted record (at P-l?) of the character corresponding to theparticular It being understood that each field on a card (Fig. 1)comprises a plurality of vertical columns of hole spaces it will beappreciated that a bank or banks of sets of instrumentalities (12s, 367,368, A, B, o, 376 and 385) would be provided in the actual machine. Aspreviously stated, each of such sets would be, or may be, identical tothe set shown in Fig. 5 so that further illustration in the present casewould constitute surplusege. A complete bank of sets of suchinstrumentalit-ies is provided with certain controlling and actuatingdevices common to the entire bank. Thus a b .i of pins 128 are releasedand restorecl by a common movable frame member 353; the sets of combs,each set comprising the combs A l). and C, are released and restored bya common movable bail 396; the sets of feeler bars, each set consisting;of fifteen bars, are released. and restored by a common set of movablebails 37$; and the sets of stored by a common movable bail 405. De vicesare also provided for causing openetion of the ty e slugs after theyhave been positioned at the printing plane P P.

These various lest mentioned instrumen talities are operated in thefollowing se quence (see Figs. 3 and 5). l/Vhen a carol. 100 has beenproperly presented, between the members 350 and 351'; the frame 353 thenmoves to the left, the comb bail 396 then. permits the combs to (hop;the feeler bar bails 379 then move to the right; the type bar bail 405then releases the type car-tiers; and the type hammers-121 are thenreleased to impel the type slugsylocking pawls 395 then" operate to holdthe type carriers against further elevation than that determined by theadvanced feeler bars. After the combs have taken their positionsdetermined by the stop members, or pin bars, the frame 353 may berestoreolto the right awaiting the next card 100, After... the typecarriers have been set in accorglance.

type carriers are released and tewith the feeler bar selected, and whilesaid type carriers are being held in such positions by the pawls 395,the restored to normal position the bail 396 after the feeler bars havebeen restored to normal osition by the bails 379. At a proper time afterthe printing has been effected the bail 405 restores the type carriersto normal position. A new card may then be presented and read and so on.

So far as comprehension of the present invention is concerned, adisclosure of timing and operating mechanism for performing the variousabove described sequential release and restoring operations is notnecessary. In fact, so far as this application is concerned it might beassumed that these operations are performed manually in the propersequence. However, I shall describe more or less generally some of themechanism employed in a complete machine. For a more specific anddetailed disclosure of such mechanism reference is to my copendingapplication Serial No. 566,448,-filed June 7 1922, entitled Recordsheets and apparatus controlled thereby of which the present applicationis a division. This last mentioned copending application alsoillustrates a bank of sets of instrumentalities, of which one set isshown in Fig. 5 of the present application.

Calling attention to Fig. 3, I shall now describe the mechanism foroperating the frame 353. Forward movement of the frame 353 is secured byitqggle levers 357 mounted upon the sides of the frame and having a link358 extending to an arm 359 fixed to a shaft 316 and having a follower359 cooperating with a cam 360 on shaft 265. The toggle is broken, andthe pins 128 released for advance, by means of a spring 361. Therestoration of the frame 353, to restore the pins 128 to normal osition,is effected by means of the cam 360.

The comb bail 396 is actuated by links 397 from crank Shaft 399 is inturn actuated by a linkage 400 which extends down outside of the mainframe of the machine into cooperation with a cam 401 on the shaft 265.

The pawls 395, one for each of the type carriers, are adapted tocooperate with the notches shown on the type carriers to hold each typecarrier down, against the action of the springs 386. At the proper timein the cycle a latch-control bail 402 fixed on a combs may be byelevation. of

hereby made shaft 403 is actuated to permit the latches to engage thetype carriers under the influence of their springs. The operating meansfor the shaft 403 will be described hereinafter.

Type bars 385 are restored in downward direction after the printingoperation by tin restoring bail 405. This bail is actuated by a link 406connected to a rocker arm 407 arms 398 on shaft 399.

having a dependim link 407 connected. to a pivoted arm 408 naving afollower cooperating with an internal cam 409 on the shaft 265. Prior tothe restoration of the type bars, the latches 395, are released. This iseffected by rocking the shaft 403 which carrier an arm 410 carrying apin adapted to be engaged by a pivoted latch 404. Downward movement of.the arm 407 causes the pin 411 carried thereb to engage an rock the arm410 gounter-c ockwise, thereby releasin the latches 395 from the typecarriers. hereafter the latch 404 engages the pin on the arm 410 andprevents relatching of the latches 395 until a second pin 412 carried bythe link 406 engages and re leases the latch 404 upon upward movement ofthe link and bail 405. This release will permit the bail 402 to swing tothe right under the bias imparted by the springs of the latches 395.

The bails 37 9, for the feeler bars, are carried by a strip 380 (Fig.16) which is moved back and forth by means of a toggle device 381 havinga follower 382 cooperating with cams 383, one on each side of themachine, on the shaft 265. The two positions of the bails 379 are shownin Figs. 3 and After any type slug 393 is brought to the printing plane-P it is impelled against an inking ribbon 420 (see Figs. 3 and 5),disposed in front of a record-receiving car or sheet 116, by means of ahammer 421. The ribbon feeding and reversing devices are not disclosedas they are of conventional form. To drive the type slugs forward, astriking pin 422 is provided, being suitably guided at the printingplane and adapted to be struck by the hammer 421 pivoted on a shaft 423.Fig. 3 shows the position of a hammer 421 prior to printing. Here it isheld in cocked position by a latch 424. When the type carrier 385 movesupwardly, the link 426 ascends, swinging the latch 428 into engagementwith the hammer lock 424. After the selected type slug hall reached theprinting plane, rocked thereby moving the latch 428 to the right whichcauses the lock 424 to turn counter-clockwise. This releases the hammer421 which swings forward under the action of its spring to strike thestriking bar 422.

It will be understood that there are a plurality ofstrikers 422, one foreach type carrier, and a corresponding number 0 hammers 421, etc. Thecocking of the various hammers 421 is effected by a common bail 425which is pivoted .upon the shaft 423, which is rocked to restore thehammers by a linkage 430 which extends to a bell crank 431 This bellcrank has a follower cooperating with a cam slot 432 in the'arm 407. Thehammer release shaft 427 is rocked at the proper time in the cycle by athe shaft 427 is 705 and their plates and pins 707 mosses suitablelinkage 423" (Fig. 17) which comprises a part -12? adapted to be engagedand operated by a pin 42'? on the cam 383 on shaft The cycle ofoperation will now be understo l. When a card field is presented at ital{Figs 3 and 5) the perforation sensing elements read the combinationarrange menits of perforations and effect a corresponding record uponthe record-receiving card or sheet 116, through the variousinstrunientalilies disclosed. As thus far described the record iseffected by printing at the plane 1 4 .lhe machine is of coursesusceptible to modification in various respecie. ld'or example, insteadof efiecting' a printed record on the cards 116, each card 116 may beperforated in accordance with the perforations in a controlling card100, or both printing and perforating may be efrecteu.

Fig. I have illustrated an arrange ment whereby, when any of the varioustype slugs 398 is presented at the printing plane P--P, perforatingdevices are operated to effect a combination arrangement ofperforations, representing the particular selected character {see thecode in Fig. 2), such perfor-aliens being effected in a card 116 vertilybelow the place at which the character is printed by the selected. typeslum To this end each type carrier 385 has connected thereto acorrespondingone of cross members T00 in turn connected to acorresponding one of bars 701 slidable in directions parallel "to thedirections-of movement of the type carriers. Avdescription of one of thebars 701 and the punching or pcrforae inp mechanism therefor, willsufi'ice for all as they are similar.

The bar 701 carries aplurality of pins 702- each of which is mounted forreciprocation upon said bar in directions at right angles to the line ofmovement of said bar 701. The pins 702 are biased to the position shownin Fig, 15 by means including compression springs, two of which areshown in dotted lines in Fig. 15. A perforated guide plate 703 and acorrespondingly perforated backing plate 704 serve to guide the sixpunches 705 "from the position shown in Fig. 15, through therecord-receiving card or sheet 118. Each of these punches has securedthereto a corresponding one of six plates 706, each of which terminatesin a corresponding one of six pins 707 slidably mounted in a stationaryguide plate 708. The individually movable punches are moved to the rightby means of a restoring bail or plate 705. It striking member 711 ismovable from the position shown in Fig, 15 to the left, and vice versaso as to operate and release the pins 702, It will be understood thatany suitable means may be pro 'ment of perforations (in printing plane,the abtuation of the member 711 to the left will operate certain of thepins 707 to advance a combination of punches 705, to effect acombination arrangethe card 116) representing the character (see thecode in Fig.

-2) printed by the particular slug at tlie printingplane P-P. F orexample, in Fig. 15, the carrier 385 is in such position as to placethe-U type slug 393 in the printing plane PP. This causes the bar '?01to assume the position shown. When the member 711 advances the pins 702and 702* engage and operate the third and fifth pins 707, respectively,and the remaining four pins 707 are not operated at this time. Advanceof the third and fifth pins 707 causes advance of the third and fifthpunches 705, the remaining four punches 705 remaining in normal positionat this time. Advance of the third and fifth punches 705 effectsperforations in the third and fifth hole spaces in that column on card116 which is vertically below the place at which the U isv 1j rintedbythe selected type slu Referring now to Fig. 2 it will be seen that acombination arrangement of perforations in which there is oneperforation in the third hole space and another in the fifth hole space,represents or corresponds to the char acter U.
